Description

Technical Field

[0001] The utility model relates to the technical field of steel structure buildings, in particular to an automatic welding device for building steel structure wall and column components. Background Art

[0002] When constructing a building, column components and wall components together constitute the main frame of the building steel structure, ensuring the stability and safety of the building. Among them, the column components adopt a columnar structure, and according to their different loads, they adopt circular, trapezoidal or rectangular cross-sectional shapes. The wall components mainly play the role of enclosure, partition and load-bearing in the building steel structure, and are formed by welding beams, columns and steel plates. Among them, both wall components and column components can be called components. When welding components, manual welding is usually used to weld wall structural members and column structural members. The speed of manual welding is slow, and the welding results will be affected by uncertain factors such as the welding level of the welders and the performance during welding, which will lead to the welding work being unable to proceed stably.

[0003] Therefore, in the prior art, an automatic welding device is often used to weld column components or wall components, such as an automatic welding device for building steel structure wall and column components disclosed in Chinese patent publication number CN206677434U. The device mainly includes a working platform and a positioning track surrounding the wall and column components and laid on the working platform. A base is rollingly connected to the positioning track on the working platform, and a column is provided on the base. The top of the column is connected to one end of a movable arm, and the other end of the movable arm is connected to a welding gun. The base moves along the positioning track in a specific direction according to preset parameters, thereby driving the welding gun to automatically weld the welds on the wall and column components. The positioning track can be flexibly adjusted according to the wall and column components to adapt to the automatic welding of wall and column components with cross-sectional shapes such as circular, rectangular or trapezoidal. However, there are still some problems in use:

Since wall components or column components need to be of different sizes according to different loads, the above-mentioned automatic welding device cannot automatically adapt to the size of wall components or column components. It is necessary to manually measure the distance between the track and the component in advance, and then lay the track to adapt to the size of the component, which consumes a lot of time and leads to low welding efficiency.

[0054] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0055] Example 1

[0056] It should be understood that since wall components or column components need to be of different sizes depending on the load, existing automatic welding devices cannot automatically adapt to the size of wall components or column components. It is necessary to manually measure the distance between the track and the component in advance, and then lay the track to adapt to the size of the component, which consumes a lot of time and leads to low welding efficiency.

[0057] Therefore, in order to improve the above problem, this embodiment provides an automatic welding device for building steel structure wall and column components, which mainly includes a frame 200, a limiting ring 300, two sliders 400, two welding parts 500 and a rotating platform 600. This automatic welding device is mainly used for automatic welding of wall components and column components (for the convenience of description, component 100 is used to replace wall components and column components in the following).

[0058] Among them, Figure 1 As shown, a plurality of beams 110 are provided on the circumference of the outer wall of the component 100, the frame 200 is arranged on the beams 110 on the outer wall of the component 100, and a first annular groove 210 is provided on the inner wall of the bottom of the frame 200, and the notch of the first annular groove 210 faces upward.

[0059] like Figure 1-2 As shown, the limiting ring 300 is arranged on the surface of the inner wall at the bottom of the frame 200, and a second annular groove 310 is provided in the limiting ring 300, and the notch of the second annular groove 310 faces the component 100, wherein two sliders 400 are both arranged in the limiting ring 300, and when the device is used to weld the component 100, the two sliders 400 are relatively and symmetrically arranged on both sides of the component 100.

[0060] Among them, Figure 1 , Figure 7 and Figure 8 As shown, the two sliders 400 are adapted to the shape of the second ring groove 310 of the limiting ring 300, so that the sliders 400 can slide relative to the second ring groove 310 and slide along the second ring groove 310. The two sliders 400 have a first groove 410, and the notch of the first groove 410 faces the component 100.

[0061] like Figure 1 , Fig. 9 , Fig.10 and Fig.11As shown, the two welding parts 500 include a connecting column 520 and a welding end 510, wherein the connecting column 520 can be a polygonal body such as a cylinder, a rectangle, etc. In this embodiment, the connecting column 520 is a rectangle.

[0062] One end of the connecting column 520 is adapted to the first groove 410, so that one end of the connecting column 520 is inserted into the first groove 410, wherein an adaptation spring 521 is provided between the end face of one end of the connecting column 520 and the side inner wall between the upper inner wall and the lower inner wall of the slider 400, and the two ends of the adaptation spring 521 are respectively fixedly connected to the end face of the connecting column 520 and the inner wall of the first groove 410, so that the adaptation spring 521 drives the connecting column 520 to displace relative to the first groove 410, and the displacement direction is perpendicular to the circumference of the component 100.

[0063] Among them, a column 530 is provided on the upper side surface of the other end of the connecting column 520, one end of the column 530 is rotatably connected to the welding end 510, and the column 530 and the connecting column 520 are perpendicular to each other. Specifically, the welding end 510 and the column 530 are connected by a rotating shaft, so that the welding end 510 can weld the component 100 from top to bottom by rotating.

[0064] The welding end 510 may be a welding gun, a welding nozzle or the like.

[0065] In this embodiment, Figure 1 , Fig. 9 , Fig.10 and Fig.11 As shown, a limiting slide 522 is provided on the lower side of the connecting column 520, and the limiting slide 522 is arranged along the axial direction of the connecting column 520. A second groove 630 is provided on the upper surface of the rotating platform 600, and the second groove 630 is adapted to the limiting slide 522. The second groove 630 is opened along the axial direction of the connecting column 520, wherein the limiting slide 522 is arranged in the second groove 630, so that the limiting slide 522 is displaced relative to the second groove 630, and then the welding part 500 and the rotating platform 600 are relatively displaced through the limiting slide 522 and the second groove 630, and the displacement direction is consistent with the axial direction of the connecting column 520 and the axial direction of the adaptation spring 521.

[0066] Among them, a driving wheel 610 and a positioning member 620 are provided on the lower surface of the rotating platform 600, wherein the driving wheel 610 and the positioning member 620 are relatively arranged at the two ends of the rotating platform 600, and the driving wheel 610 is abutted against the inner wall of the bottom of the frame 200, and the positioning member 620 is arranged in the first annular groove 210. Specifically, the positioning member 620 can adopt a rectangular block, a cylindrical block or the like. In this embodiment, the positioning member 620 adopts a rectangular block, and the positioning member 620 is adapted to the second annular groove 310, so that the positioning member 620 is inserted into the second annular groove 310, and the positioning member 620 can slide along the second annular groove 310.

[0067] In this embodiment, Figure 1 and Fig.14 As shown, the outer wall of the positioning member 620 is provided with a plurality of rolling grooves, and the plurality of rolling grooves are arranged in sequence and at intervals, wherein a second ball 621 is provided in the rolling groove, and a compression spring 623 is provided between the second ball 621 and the inner wall of the rolling groove, so that the second ball 621 can be displaced relative to the rolling groove.

[0068] Among them, the second ball 621 adopts a spherical structure, and the center of the second ball 621 is set in the rolling groove, so that the rolling groove wraps most of the outer wall of the second ball 621, and the groove opening of the rolling groove is set at one end of the second ball 621 close to the inner wall of the first annular groove 210, so that the second ball 621 cannot fall from the first groove 410. At the same time, the relative force between the positioning member 620 and the inner wall of the first annular groove 210 can be adjusted by the compression spring 623 when the positioning member 620 moves along the first annular groove 210.

[0069] In this embodiment, Figure 1 and Fig.13 As shown, a driving motor 611 is provided on one side of the driving wheel 610 for driving the driving wheel 610 to rotate, wherein the rotation speed of the driving wheel 610 can be controlled by adjusting the rotation speed of the driving motor 611 .

[0070] In this embodiment, when the component 100 is welded, the frame 200 is set on the multiple beams 110, and the welding end 510 of the welded part 500 is abutted against the welding part of the component 100 through the action of the adaptive spring 521. The welding position can be further adjusted by rotating the welding end 510 up and down. At this time, the welding end 510 is abutted against the component 100, so that the connecting column 520 is squeezed by the welding end 510, so that the connecting column 520 squeezes the adaptive spring 521, and then the adaptive spring 521 is compressed, so that the adaptive spring 521 exerts pressure on the welding end 510 through the connecting column 520. The force causes the welding end 510 to counteract the component 100, and then the driving wheel 610 is started to rotate at a predetermined speed. At the same time, the driving wheel 610 drives the rotating platform 600 to rotate along the first annular groove 210 through the action of the positioning member 620, and the welding piece 500 is rotated through the action of the second groove 630 and the limiting slide 522. Then, the welding end 510 is started to weld the component 100, so that the welding piece 500 automatically welds the component 100, and can also adapt to components 100 of different sizes through the adaptation spring 521.

[0071] The two welding members 500 , the two sliding blocks 400 , and the two rotating platforms 600 are all symmetrically arranged relative to the component 100 .

[0072] In this embodiment, the welding piece 500 is driven to rotate by the rotating platform 600, so that the welding piece 500 automatically welds the circumference of the outer wall of the component 100. At the same time, through the action of the limiting ring 300, the slider 400 and the connecting column 520 of the welding piece 500, the welding piece 500 can automatically adapt to components 100 of different sizes, thereby avoiding the operator from manually abutting the welding piece 500 against the component 100, thereby improving the efficiency of the welding work.

[0073] Example 2

[0074] In order to prevent the welding end 510 from being damaged due to a large force when the welding end 510 directly contacts the component 100 under the action of the adaptive spring 521, according to the automatic welding device described in the above embodiment, in this embodiment, Figure 1 , Fig. 9 , Fig.10 and Fig.11 As shown, a travel wheel 523 is provided at one end of the connecting column 520 away from the limiting ring platform 300, and the travel wheel 523 abuts against the outer wall of the component 100, and the welding end 510 abuts against the component 100, wherein a travel motor 524 is provided on one side of the travel wheel 523 to drive the travel wheel 523 to move.

[0075] In this embodiment, since the walking wheel 523 is against the component 100, the force applicable to paralysis of the welding end 510 is small, but the welding end 510 is still against the component 100, thereby ensuring that the welding end 510 is stably welded and avoiding damage to the welding end 510 by a large force.

[0076] The running wheel 523 rotates, and under the action of the driving wheel 610 and the positioning member 620, the running wheel 523 rolls on the outer wall of the component 100, thereby reducing the friction between the running wheel 523 and the component 100 and preventing the component 100 from being damaged.

[0077] The outer walls of the driving wheel 610 and the running wheel 523 are both provided with rubber pads 1000 , so as to prevent the driving wheel 610 from causing damage to the frame 200 and prevent the running wheel 523 from causing damage to the outer wall of the component 100 .

[0078] Example 3

[0079] In order to reduce the friction between the slider 400 and the limiting ring 300, thereby preventing the slider 400 from being displaced relative to the limiting ring 300, according to the automatic welding device described in the above embodiment, in this embodiment, Figure 1 and Fig.12As shown, a plurality of first balls 420 are disposed on the outer wall of the slider 400 , and the plurality of first balls 420 respectively abut against the inner wall of the limiting ring 300 , and the first balls 420 rotate relative to the slider 400 and the limiting ring 300 .

[0080] Among them, when the slider 400 is displaced relative to the limit ring platform 300, multiple first balls 420 are displaced relative to the slider 400 and the limit ring platform 300, so that the contact area between the slider 400 and the first balls 420 is smaller, and the sliding of the slider 400 relative to the limit platform is converted into the rolling of the first balls 420 relative to the slider 400 and the limit ring platform 300, so that the displacement of the slider 400 relative to the limit ring platform 300 makes the friction smaller, and further makes the relative displacement between the slider 400 and the limit ring platform 300 easier.

[0081] Example 4

[0082] It should be understood that during welding, gas will be generated, which will be inhaled by people or drift into the environment and will have an impact on the human body or the environment. Therefore, in order to improve the above problem, according to the automatic welding device described in the above embodiment, in this embodiment, Figure 1-Figure 6 As shown, the upper end of the frame 200 also receives a sealing end cover 700, wherein the sealing end cover 700 is adapted to the frame 200, and the sealing end cover 700 and the frame 200 are detachably connected, and the inner wall of the frame 200 and the inner wall of the sealing end cover 700 are both in contact with the outer wall of the component 100, so that the gas generated during welding is sealed by the frame 200 and the sealing end cover 700 and cannot float out of the frame 200 and the sealing end cover 700.

[0083] In a more complete solution, the present invention also includes an air suction piece. An exhaust hole 220 is provided on one side of the frame 200. A sealing cover 230 is provided on the exhaust hole 220. The sealing cover 230 and the frame 200 can be connected by threaded connection, snap-on connection, etc. When welding the component 100, the sealing cover 230 is removed, and the exhaust hole 220 is connected to the air suction piece through a pipe, so that the gas generated in the frame 200 is sucked into the air suction piece, and finally processed uniformly.

[0084] The air suction component includes an air suction pump and an air storage box, and the air storage box and the exhaust hole 220 are connected through the air suction pump and a pipeline.

[0085] In this embodiment, the shape of the inner wall of the sealing gasket 800 may be circular, rectangular, trapezoidal or other shapes, so that the sealing gasket 800 is compatible with the component 100 .

[0086] Among them, the inner wall of the sealing end cover 700 and the inner wall of the frame 200 in contact with the component 100 are both provided with a plurality of card grooves 900, and one side of the sealing gasket 800 is provided with a plurality of snap-in protrusions 810 adapted to the card grooves 900, so that the two sealing gaskets 800 can be snap-fitted with the sealing end cover 700 and the frame 200 through the snap-in grooves and the snap-in blocks, thereby making it easier to replace the sealing gaskets 800, and further allowing the welding device to weld irregular components 100 by replacing the sealing gaskets 800, so that the welding device has a wider range of applications.
